IMPROVEMENT IN MACHINES FOR SURFACE-SIZING FIBROUS MATERIALS.

Specification forming part of Letters Patent No. 43,765, dated August 9, 1864.

To all whom it may con/cern.:

Beit known that I, WILLIAM FUzzA'RD, of Malden, in the county of Middlesex and State of Massachusetts, have invented a new and useful Improvement in Machinery for Surfacing Fibrous Materials; and I do hereby declare that the following is a full, clear, and exact description of the same, reference being had to the accompanying drawings, forming part of this specification, in which- Figure lis a front view of my invention; Fig. 2, a vertical section of the same, takenin the line .fr Fig. l.

Similar letters of reference indicate corresponding parts in the two figures.

This invention relates to a new and useful improvement in machinery for applying glazing or size to brous materials, such as cotton, wadding, Ste. The invention is chieily applicable to a machine for which Letters Patent were granted to me, bearing date January 12, 1864; but it may be used in any machinery for the above-mentioned purpose ink which the yglazing or sizing is thrown upon a. cylinder, over which the web to be surfaced or sized passes, or when thrown directly upon the web itself.

The invention consists in the employment or use of a revolving brush-cylinder, or its equivalent, in connection with an adjustable roller or bar, so arranged that the glazing or sizing may be thrown upon the cylinder or web at different points, as circumstancesmay require.

The invention further consists in using, in connection with the brush-cylinder Aand the roller or bar above specified, a shield or guard so arranged as to serve as aguide or form a passage-way for the sizin g from asizingsupp`y roller to the adjustable roller or bar, from which place or point the sizing is discharged upon the cylinder or web.

To enable those skilled in the art to fully understand and construct my invention, I will proceed to describe it.

A represents a box in which the glazing or sizing is placed-the kind usually employed for glazing or sizing cotton goods-and (l is a roller which is fitted in said box and is partly 'submerged in the glazing or sizing.

D is a brush-cylinder, which is placed over the roller G and works with the points of its bristles in conta-ct with the surface of said roller. The journals of this brush are fitted and work in side pieces, c a, which extend upward from the box A, and in each side piece a, above the brush-cylinderD, there is made a curved or segment slot, b, in each of which a set-screw, c, is fitted, said set-screw passinginto bars d d, the lower ends of which are fitted loosely on the shaft ax of the brush-cylinder, which is at the center of circlesl of which the curved slots b form parts. In the upper ends of the bars d d the shaft f of a roller, E, is fitted and allowed to work or rotate freely. This roller E has such a relative position with the brush-cylinder D that the bristles g of the latter will come in contact withit and be somewhat deflected thereby, as shown clearly in Fig. 2. I

F is a guard or shield, which may be con structed of sheet metal, and is connected at its upper end to the shaft f of roller E. This guard or shield is curved and extends down into the box A, as shown in Fig. 2.

The operation is as follows: The brushcylinder D is rotated in the direction indicated by the arrows,'and is supplied with glazing or sizing from the roller G, and the bristles of the brush-cylinder, as they come in contact with the roller E, are bent back, and as they pass said roller they quickly assume by their elasticity their former position, and in so doing discharge the glazing or sizing in a thin sheet upon 4the cylinder or web. In Fig. 2 a portion of a cylinder is shown in red outline. The position of the roller E determines the point on the cylinder or web upon .which the glazing or sizing is cast, and by varying the position of this roller, which is done by loosening the set screws c c and moving the bars d d, the glazing or sizing will be thrown at a higher or lower.point, as the impelled sheet of the latter is at a tangent with the brush-cylinder D and roller E at their points of contact. (See Fig. 2.) The guard' or shield F prevents the glazing or sizing being cast or thrown off from the brush-cylinder at the back part ot' the same, and it also forms a draft-chamber and assists in controlling and drawing upward the glazing or sizing to the roller F.

Instead of a roller, aiixed or non-rotatingbar may be used; butlprefera roller, as it prevents the glazing or sizing from accumulating upon it and hardening, as all parts of its surface are kept moving and brought in contact with 2 l 43,765 Y y f1 merged roller, C, and an adjustable roller or bar, E, arranged to operate in them-manner substantially as and for the purpose herein set forth.

2. The shield or guard, arranged and combined with the brush-cylinder, or its equivalent, and with the roller or bar E, to operate as and for the purpose described.
